Study of the power parameters of the working bodies of tillage machines
Abstract
The article presents data on the resistance of the working bodies of tillage machines, which are determined by dynamometry of the tool as a whole. The design of a dynamometric trolley of a small soil channel is proposed, which makes it possible to perform spatial dynamometry of the working bodies of tillage machines, i.e. finding the magnitude, direction and point of application of the resultant soil resistance forces. The method of studying the force loading of the attachment elements of the working bodies on the cultivator-plant feeder bead bar is considered. Force and linear parameters are taken as criteria that determine the stress state of fastening elements. Selected strain gauge structures that should be installed on the bar of the beams to receive and register vibrations and force loading of the attachment elements of the working bodies. A grapho-analytical method is proposed for calculating the parameters of a dynamic screw to determine the components of soil resistance forces and moments at individual points.
